Disparities of Breastfeeding patterns between Black and White Adventist Women in North America. Results from the Adventist Health Study (AHS) - 2
Bibliographic record
Abstract
Background: Racial disparities of breast feeding have been reported in various studies, but few have evaluated the factors associated with racial discrepancies in breastfeeding. Method: We evaluated breastfeeding patterns among 26,926 white and 10,550 black porous females, aged 30 years and above, who were enrolled in the Adventist Health Study-2, a cohort of about 96,000 health conscious subject across the US and Canada. Two outcomes were evaluated: 1) initiation of breastfeeding and 2) length (months/child) of breastfeeding using log linear binomial and multiple linear regression, respectively. Analyses were adjusted for age, education, parity, body mass index, marital status, country lived during young adult life (age 6-16), oral contraceptive use and dietary patterns. Results: Black women were less likely to initiate breastfeeding than white women (Prevalence Ratio=0.87, 95% Confidence Interval: 0.86-0.89) and breastfed on average 1.2 months shorter per child than white women. Older women were less likely to have breastfed their children (PR=0.97, 0.91, 0.87 and 0.95 for ages 41-50, 51-60, 61-70 and 80+ respectively compared to 30-40 year olds Vegetarians were more likely to initiate breastfeeding than non-vegetarians (Prevalence ratio= 1.07-1.12) Other independent predictors of initiation of/duration of breastfeeding were age, education, living outside of the US at age 6-16, parity, marital status, BMI and oral contraceptive use. Conclusions: Black women were less likely to initiate breastfeeding and, if breastfeeding, did so for fewer months than white women. The racial difference remained virtually unchanged even after adjusting for a number of socio-economic factors including age, marital status, education and place lived during childhood and adolescence. The observed racial disparity warrants further study into possible factors that can explain the differences seen. Attitudes towards breastfeeding, in particular, need to be investigated among black and white females in the US. Key words: disparity, blacks, white women, breastfeeding, Adventists, North America.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
